<h3>概述</h3>

    <p>本模块用于控制传送给CGI脚本和SSI页面的环境变量。所传送的环境变量可以来自调用<code class="program"><a href="../programs/httpd.html">httpd</a></code>进程的shell ，或者来自在配置过程中所设定(set)或撤销(unset)的变量。</p>

    <p>从调用<code class="program"><a href="../programs/httpd.html">httpd</a></code>进程所在的shell中，指定一个或者更多个环境变量，传送到CGI脚本和SSI页面。例如：</p>

    <div class="example"><h3>示例</h3><p><code>
      PassEnv LD_LIBRARY_PATH
    </code></p></div>

</div>
<div class="top"><a href="mod_env.html#page-header"><img alt="top" src="../images/up.gif" /></a></div>

    <p>设置一个环境变量，该变量将会传送到CGI脚本和SSI页面。例如：</p>

    <div class="example"><h3>示例</h3><p><code>
      SetEnv SPECIAL_PATH /foo/bin
    </code></p></div>

</div>
<div class="top"><a href="mod_env.html#page-header"><img alt="top" src="../images/up.gif" /></a></div>
